Buying Guide
What wattage do you actually need?
Determine essential circuits and appliances. Start with your highest surge load and compare it to your generator’s peak watts. If you routinely run air conditioning, water heaters, or sump pumps, prioritize models with higher surge and ample running watts.
Fuel flexibility: Do you need tri‑fuel or dual fuel?
Tri‑fuel generators offer the broadest fuel compatibility, useful during fuel shortages. Dual‑fuel units cover gasoline and propane, providing versatile options for different situations and storage conditions.
Portability and footprint
Consider the unit’s weight, wheel kit availability, and overall footprint. Higher wattage units are often heavy; plan for a portable setup with stable, level ground and access to 120/240V outlets and transfer switches.
Start method and maintenance
Electric start with backup recoil is convenient, especially in emergencies. Look for a digital hour meter, low‑oil shutdown, and CO detectors for safety. Regular maintenance intervals help sustain performance during outages.
Transfer switches and safety features
Choose models with transfer‑switch compatibility and safety features such as rubber outlet covers and CO sensors. Confirm that your home’s electrical panel can accommodate the generator’s amperage and outlet types.
Runtime considerations
Runtimes depend on tank size and load. For longer outages, select models with larger fuel tanks or the option to pair with a readily available fuel source. Consider fuel storage and access when choosing between gasoline, propane, and natural gas options.
What about warranties and service?
Examine manufacturer coverage, dealer support, and service availability in your region. Quiet operation, noise levels, and ease of part replacement can influence long‑term satisfaction.

FAQ
- What kind of generator do I need for a typical home outage?
Choose a model that can handle your essential loads (fridge, well pump, lights) with adequate surge watts and at least 8–12 hours of runtime on a full tank.
- Is tri‑fuel more reliable than dual fuel?
Tri‑fuel offers greater fuel flexibility in emergencies, but dual‑fuel units still cover many scenarios and are usually more compact and affordable.
- How do I determine the transfer switch size?
Match the generator’s amperage and outlet configuration to your main electrical panel and the required circuits you plan to power during outages.
